- Stop at the stand pipe
- Help pipe guy with high rise pack
- Double males to the FDC
- Hook up primary and secondary and pull extra
- Pull off to the hydrant and nose in
- Engage the pump
- Wheel chock
- Tank to pump
- Break prim/sec and connect to discharges with double females
- Hook up big to the hydrant
- Open intake slowly
- Charge standpipe system when ready and adjust pressure as needed
- Crack tank to fill

20,10,7 rule
After opening the first attack line of the pressure drops
20% you can pump 1 line of equal or less
10% 2 lines of equal or less
7% 3 lines of equal or less
Deck gun
80 psi nozzle
15 psi appliance
5 psi elevation
Air bound
- shut down lines and prime
- crack deck gun
If there is a issue with hydrant pressure
- Radio in urgent message
- shut down exterior lines
- pull tank to pump as your safety net

Why and when do we close the tank to pump at engine 4?
- Close it after getting a positive water supply
- We close it as a safety net so we know if there is a issue with water coming into the pump
- Open it back up to give 500 gallons for egress
Hose bed
Supply lines:
-28 3” lengths total (1400 ft.)
-50 ft. Per length
-14 lengths each primary and secondary (700 ft. each)
Attack lines:
-Primary attack line 1 3/4” 250 ft. 5 lengths (smooth bore)
-Secondary attack line 1 3/4” 250ft. 5 lengths (fog nozzle)
-2 1/2” 250 ft. 5 lengths (smooth bore)
Forward lay (Hydrant to fire or dragging back)
- Pull just past the hydrant
- Hydrant guy ropes it and waves off the engine
- Pull a building and a half past the fire building and leave room for the truck
- Put it in pump
- Tank to pump
- Chock the wheel
- Help clear the bed
- Charge lines and adjust pressure whenever water is called for
- Break primary (go underneath) connect to inlet
- Call for one and open the inlet slowly adjusting pressure as needed
- Close drain valve
- Close tank to pump
- Crack tank to pump
- Break secondary (go underneath) connect to inlet
- Call for 2 and open inlet slowly
- Close drain valve
- OPTIONAL (call for both at the same time)
- Set pressure relief valve
Reverse parallel lines (fire to hydrant or reversing out)
- Pull up with the tail board in the middle of the fire building
- Let the everyone out and help clear the bed
- Hydrant guy gets back in and officer kneels on the lines and waved us off
- Stop past the hydrant and pull ebrake
- Put it in pump
- Tank to pump
- Wheel chock
- Break primary
- Attach to discharge with double female
- Charge lines and adjust pressure when the call for water
- Break secondary and connect to discharge
- Pull enough primary and attach it to inlet
- Call for one and open inlet slowly keeping a eye on pressure
- Throttle down if necessary
- Close drain valve
- Close tank to pump
- Crack tank fill
- Set pressure relief valve
- Pull enough primary for overlay
- Open the gate and then open the inlet slowly
- Close discharge valve
Reverse hook up big (reversing out or fire to hydrant)
- Pull up with the tail board in the middle of the fire building
- Let the everyone out and help clear the bed
- Hydrant guy gets back in and officer kneels on the lines and waved us off
- Hydrant guy guides you into the hydrant
- Ebrake
- Put it in pump
- Tank to pump
- Chock the wheel
- Break the primary and attach to discharge with a double female
- Charge line and adjust pressure when called for
- Break the secondary and attach to discharge with a double female
